[media] saa7115: initialize demod type and add the needed pads
The saa7115 driver is used on several em28xx-based devices. Now that we're about to add MC support to em28xx, we need to be sure that the saa711x demod will be properly mapped at MC. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
